ZAHROLUDi AZ OKSIDI KARBON

zahroludi-az-oksidi-karbonZAHROLUDi AZ OKSIDI KARBON. Zahroludii shadid az oksidi karbon dar natijai vayron kardani qoidahoi istifodai bukhori (barmahal pushonidani dudkash, dar mavridi vayron budani on, sukhtor, ikhroji gaz va g.) ba amal meoyad. Garchand Z. kam duchor oyad ham, holo dar dehot joy dorad. Zahroludii shadide, ki hangomi sukhtor az oksidi karbon ba amal omadaast, khele vaznin meguzarad. Hodisahoi zahroludi az gazhoi moshin (onho to 10 foiz gazi karbon dorand) hangomi kori muharriki avtomobil dar garaj, inchunin mavridi duru daroz nishastan dar kabinai avtomobil yo daruni avtobuse, ki darhoyash pushidaand, ruy medihad.
Oksidi karbon (SO) gazi berang buda, dar shakli kholis buyi susti sirpiyozro dorad. Odam onro hangomi nafas giriftan his namekunad, az in ru zahroludi noayon faro merasad. Oksidi karbon zahri qotil buda, avvalo ba khun, sipas ba sistemai asab, boftai mushakho, dil zarar merasonad. Oksidi karbone, ki az shush ba khun guzashtaast, ba gemoglobin nisbati oksigen 200 – 300 marotiba teztar tasir rasonda, payvasti ustuvori karboksigemoglobin hosil mekunad. Gemoglobin bo oksidi karbon payvast meshavad va qobiliyati az shush ba boftaho burdani oksigenro az dast medihad. Ikhtiloli faoliyati khun boisi norasoii oksigen dar boftaho, pesh az hama dar magzi sar, megardad. Az sababi kam shudani miqdori oksigeni khun nafastangi ogoz meyobad.
Z.-ro atfol, zanoni homila, ashkhosi giriftori bemorihoi shushu dil khele vaznin az sar meguzaronand. Agar miqdori oksidi karbon dar tarkibi havo ziyod boshad (beshtar az 10 mg/l), dar on surat odam yakbora behush gashta, marg faro merasad. Bisyor vaqt nishonahoi Z. tadrijan inkishof meyoband. Avvalin nishonahoi on dardi sar (bazan dardi khele sakht), sarcharkhzani, guvvosi gush va siyohi zadani chashm ast. Agar tasiri oksidi karbon qat nagardad, zafi umumi, sulfai khushk va qay padid meoyad, vale odam az hush nameravad. Mumkin ast tahayyuj payvasta bo firebi bosira va somea paydo shavad; beholi, ruhaftodagi, khoboludi avj megirad. Dertar odam behush gashta, pust surkh, mardumaki chashm vase meshavad; nafas avval khirrosi va tez, sipas ruyaki va noayon ast.
Dar mavridi Z. osebdidaro favran ba havoi toza barovarda, ba takhtapusht mekhobonand, girebon va kamarbandashro mekushoyand. Duru daroz nafas kashidani oksigen behtarin vositai tabobat ast. Agar imkon boshad az dorukhona bolishti oksigendor ovardan lozim. Ba peshoni va qafasi sina yakh memonand. Agar zarardida az hush narafta boshad, pas ba u choi garm va qahva medihand. Ba shakhsi behush pakhtai bo spirti navshodir tarkardaro ehtiyotkorona buy mekunonand. Dar holati nabudani nafas yo yakbora qat shudani on favran ba nafasdihii suni (bo usuli dahon ba dahon yo dahon ba bini) shuru menamoyand. Badi in hama osebdidaro zud ba muassisai tabobati mebarand.
Tadbirhoi peshgirii Z.: zich pushonidani darichai bukhori; ba kor nadarovardani motori avtomobil dar mavridi pushida budani dari garaj; bisyor nanishastan va khob naraftan dar moshine, ki darhoyash basta va motorash kor karda istodaast.
